Title: Synchronous circuit
Inventor: TANAKA YUUJI
IPC: G01J1/44
Filed: 1980-06-12
Abstract: PURPOSE:To enable a periodically fluctuating light to be accurately measured, in a digital photometry, by forming a synchronizing signal from the periodically fluctuating light. CONSTITUTION:The light from a TV picture surface 1 is photoelectrically converted 4 through an optical chopper 2, smoothed 6, V/F-converted 7 and counted 9 through gate 8 to obtain a picture data. The opening and closing positions of the chopper 2 are detected 15, and said detection signals are differentiated 17 and 18 to from an trigger signal for a mono-stable oscillator 20. The output thereof is used to reset the counter 9 and a synchronizing signal counter 12. The output of a TV picture synchronizing signal detector 10 is shaped 11 into a square wave and counted 12. Said count value is decoded 13 to trigger an FF14. The output thereof is applied to the AND gate 8. Accordingly, the light pulse component synchronized with the TV synchronizing signal is applied to the counter 9.

Title: Semiconductor laser array device
Inventor: YAMAMOTO ATSUYA
IPC: H01S5/40
Filed: 1986-04-04
Abstract: PURPOSE:To faciliate monolithic integration be a method wherein a plurality of lasers with double-hetero structures containing active layers are formed on a semiconductor substrate and the thickness of end plane reflection coatings on the cavity planes of one side are made different for the respective lasers. CONSTITUTION:A P-type GaAs buffer layer 7, a P-type AlGaAs cladding layer 6, an AlGaAs active layer 5, an N-type AlGaAs cladding layer 4, an N-type GaAs cap layer 3 and an AlGaAs isolation layer 2 are successively grown on a conductive P-type GaAs substrate 8. Then, stripe structures are formed in the AlGaAs isolation layer 2 by chemical etching. In this state, electrodes 1 and 9 are formed on the N-type side and the P-type side respectively. If the substrate is cleft into array-shape and fixed to a fixing jig 11 and subjected to sputtering, the thickness of the coating film become thinner near the position where the height of the fixing jig 11 is higher. Therefore, the thickness of the coating film can be controlled by controlling the angle and the position of the jig 11. As the reflectance of the respective end planes of the lasers are different, the extra process such as changing oscillation wavelength becomes unnecessary.

Title: Refrigeration air conditioner
Inventor: YAMADA HIDEHIKO
IPC: C10M105/06
Filed: 1996-04-01
Abstract: PURPOSE: To improve handling properties of an application oil, an impregnation oil and an assembly oil and electric insulation properties by using a lubricating oil which has no miscibility with a refrigerant mainly composed of hydrofluorocarbon, whose viscosity is low and whose specific gravity is lighter than that of the refrigerant, and closing an on-off valve provided between an evaporator and a compressor when the operation of the compressor is stopped. CONSTITUTION: In order to improve slipperiness of wires and winding work, a hard alkylbenzene oil is applied to the wires, and sintered parts such as a cylinder 16 and a bearing 17, which form a compression chamber, are impregnated with the hard alkylbenzene oil. Further, even when sliding parts of a compressor main body are assembled, they are lubricated with the benzene oil. Also, a refrigerator which uses an HFC 134a as a refrigerant uses the hard alkylbenzene oil as a refrigeration oil 6 for a compressor 1. The refrigerant compressor 1 in such a construction can keep moisture absorbability at a low degree because the hard alkylbenzene oil is used as an application oil and an impregnation oil or an assembly oil, for each chamber, and makes no difference from use of a conventional CFC 12 refrigerant whatsoever.

Abstract: PURPOSE:To generate accurate distance between an electron beam controlling means and a fluorescent screen and provide possibility of well complying with large size construction of a device concerned by furnishing a flat metal plate pinched by a glass container with a fixing means for the electron beam controlling means. CONSTITUTION:A fixing means 3 for an electron beam controlling means 4 is secured to of flat metal plate 2 by means of welding, etc., and the controlling means 4 is fixed to the fixing means 3. Because of provision of the flat metal plate 2 with this fixing means 2, the distance between the controlling means 5 and a fluorescent screen 6 is determined only by accuracy of parts relative to the height of the fixing means 4 wherein plane is used as reference, and a very high distance accuracy is obtained. Even though the whole device is to be constructed in a large size, the difference between the inner and outer pressures does not act on the metal plate 2 because it is pinched by glass containers 1a, 1b situated oppositely to each other. Thereby the metal plate 2 can be made sufficiently thin, and there is no risk of destroying the glass containers 1a, 1b by the thermal stress and weight can be reduced.
